Nea ccs stock fitment problem

In case anyone has trouble fitting this stock on their ar15 lower receiver because the anti rotation peg on the Nea ccs won't fit in hole in the rear of the receiver.
The ccs stock won't fit my Anderson lower and a DD lower, however it will fit on a Norc.(Norcs maybe have looser tolerances?)
The Nea anti rotation peg measures at .500" plus or minus .001" and the Anderson, DD anti rotation hole measured at .495" - .497".
I did email NEA and their response was my receiver was out of spec., fair enough.
Enlarging the receiver hole was not a option, so the only recourse was to get the peg machined down to .494", a machinist friend had to make a mandrel to be able to get it on his lathe(after stripping the stock down) to machine the peg down. I could have hand filed it down, but would end up looking like a dog's breakfast.
Another point is the telescoping arms are fairly soft steel and the notch gets peened over every time it locks in, just file the edges, so the stock collapses easily.
Have pictures, but don't see a option to add them.

I had the same issue and the word from NEA themself was that ALL of their stocks were out of spec. They advertise that theirs will fit any milspec lower. The knuckle hole on the lower is spec'd to .499" + .004. I measured my Colt Canada and it was exactly .499. The knuckle on the CCS measured .503. In order to fit milspec, the knuckle MUST be smaller than the lowest end of the tolerance (.499). NEA requested I send my lower and they would install it. They were going to grind down the knuckle which they admit would remove the finish. I declined and got my money back.

I measured the knuckle on other stocks and they were all below .490 and all fit my lower perfectly. I ended up getting a Maxim CQB stock which included a JP captured buffer system. Pricey but puts the CCS to shame in all departments except a bit longer. But it doesn't really matter how cheap the CCS is when you cannot install it.

Absolutely true,cheap is cheap I shouldn't have had to get it machined to get it to fit, but I bought it from a fellow nutter because it did not work on his setup. Now I know why, it wasn't his fault.
 
Personally, I blame NEA for this. As per their website:

Q: Will your components work in any AR-15?

A: Our components are made to meet or exceed the MIL-Spec and are compatible with any standard AR-15 rifle.

So ask yourself, is my AR15 a standard AR15? Mine sure is and it didn't fit mine. And they admitted that none of their CCS stock would fit my receiver. I purchased mine new and NEA was horrible about it all. They ignored emails from me and the retailer. Eventually the retailer got fed up and refunded me the money before NEA shipped it back.

Too bad you altered it yourself. That voids their warranty. Their warranty isn't exclusive to the original buyer. They admitted that grinding down the knuckle would remove the finish (which protects the part), and made no mention of refinishing the part, so the part was compromised and that was contrary to what I was sold. That's why I wanted my money back.

With all the out of spec parts I have seen on their AR15s, I'm surprised they are still in business. I was foolish to think that the CCS would be different.

As an aside, the rails on the CCS rubbed on my lower as well which would have worn away the finish on my lower. I couldn't find the milspec for the width of an AR15 at that section of the lower, so I didn't make an issue of it.

NEA, stay away!!! Hey, that rhymes. Should be their motto
 
I just used a reamer in a cordless drill to ream out the hole ever so slightly

Then I ended up selling it before I even used it, and bought a TROY stock kit instead. The NEA quality was terrible, their gas key staking was a joke!
 
The email I got back from NEA was that my receiver was at "not to spec" so they are not admitting to any fault.I hate having to fight with anyone, if I can fix it at my end, I will do that.
Seems like their fix is like a butcher job "grinding"? Mine only took .006"(.003" cut) off the diameter of the peg on a lathe and only took the finish off the peg ,which was very little.
I guess corrosion could set in, if left unattended, a little bit of grease could probably fix that.
Just bad P.R. and product development on NEA's part. Always listen to customer feedback and improve your product.

Mine did not fit more then one lower I had on hand at the time, one was a DD MK18 lower the other a Wilson Combat billet upper/lower set

I guess NEA thinks all our lowers our out of spec LOL

When I did ream my lower, it was also really just the coating that had to come off for it to fit. No actual aluminum had to be machined. It wasn't way out but it was out of spec

_Exceed_ - they keep using that word, but it really doesn't mean 'larger than' MIL-Spec which is what they seem to be doing :p
